The program 'esp_mesh_sdk_app_light' i want to use does not work.
First i got the error: `.irom0.text' will not fit in region `irom0_0_seg'.
So i changed the 'eagle.app.v6.ld' to org = 0x40210000, len = 0x6C000
the problem here is that you write over the space between 3E000 and 40000 (master_divice_key.bin space)

my question is, how can i fix it? or is the only solution make the code smaller?
